Objective
Researchers at Marshall Space Flight Center have developed a series of technologies for making and detecting images of two-dimensional matrix symbol patterns used to identify and track manufactured items.
Description
These matrix symbols can be hidden from view (e.g., beneath coatings or on the backside of a surface) or embedded in an assembly. As part of an automatic identification scheme, these matrix symbols offer high information density and security.
Benefits
• High-density information—The encoded information can be 100 times more detailed in the 2-D format than with traditional bar code technologies.
• Unique reading capabilities—These technologies can be used to read symbols beneath coatings, laminates, and foams and in low-light environments.
• Increased security—Because the matrix is marked directly on the surface, codes cannot be removed, altered, or falsified. And, the symbols may be layered in an ultrasecure, stacked arrangement.
• Comprehensive—These technologies expand the range of materials that can be marked with encoded information.
Current Capabilities
Current capablities can be adapted to include: aerospace, airplane parts, automotive, computer chips, designer clothing, electronics, guns, jewelry, scuba tanks, tires, and welding tanks.
Technical Basics
These technologies stemmed from work at NASA Marshall Space Flight Center to develop visible marks for tracking Space Shuttle parts for lifetime analysis. NASA needed an identification system that enabled more detailed information to be coded than with traditional bar code technology. MSFC’s solution was the use of a 2-D matrix symbol that carries up to 100 times as much information in the same amount of space. Researchers went on to develop five technologies that enabled the detection of “invisible” 2-D matrix symbols. Symbols embedded beneath protective coatings or within assemblies for security, aesthetic, and symbol-protection reasons can be read using these technologies. The marking materials, which are applied directly to the surface, differ from the base material in the detection characteristic (e.g., acoustic impedance properties, infrared emission).
Potential Application(s)
• Aerospace
• Airplane parts
• Automotive
• Computer chips
• Designer clothing
• Electronics
• Guns
•Jewelry
• Scuba tanks
• Tires
•Welding tanks
Technology Commercialization Status
These technologies are part of NASA’s technology transfer program. The program seeks to stimulate development of commercial uses of NASA-developed technology. MSFC has patented, or filed for patent, on the five detection technologies and the stacked symbol technology. NASA invites companies to license or to consider a partnering arrangement where NASA and the licensee share development costs.
